Cat Getting Flea Medicine

If you have been a cat parent for any amount of time, you have surely had to deal with fleas at one time or another with your cats.

This is especially true if your cat spends any amount of time outdoors. Fleas cannot only be a huge inconvenience, they can lead to bigger problems if they are not treated.

Fleas can cause itching and discomfort, but they can also lead to anemia and organ failure in kittens if they are not treated. The best flea treatment for cats can be an over-the-counter treatment or a natural flea treatment.

Checking your cat for fleas regularly is one of the best ways to keep these pesky critters under control. It is much easier to get rid of fleas when there are one or two than when they become a crowd.

Once they begin to multiply and lay eggs on your cat and in your house, this can turn into a process that can take months to resolve.

If you have cats that spend even a few minutes outside or spend time around dogs, a flea treatment should be part of your cat’s regular health treatment.

The Complete Guide to Choosing a Flea Treatment for Your Cat

Fleas are more than just a minor inconvenience. They can make your cat sick and uncomfortable. They can also become part of your household biting you and members of your family. 

But it doesn’t have to stay that way. Some products can give your cat comfort and help you clean up your home.

Do All Cats Get Fleas?

It is common for animals to have fleas, especially if they go outside or are exposed to other animals. Fleas live on animals. They will not live on humans because they do not have fur.

You may wonder if your cat will get fleas. Not necessarily. They have to be exposed to fleas in order to get them. I have 2 cats that are 13 years old and they have never had fleas.

Now, with that said, just because your cat does not go outside does not guarantee he will get fleas. Cats that are strictly indoor cats, can get fleas if they are exposed to them.

They can be brought into a home by another pet. They can also be obtained from a home that has fleas or flea eggs in it. No one’s cat is immune to fleas, but that does not mean they are guaranteed to get the pests.

Depending on the pet’s lifestyle, some people will treat their pets monthly as a precaution.

If you have strictly indoor cats that are not treated for fleas as a precaution, it is still important to be able to recognize the signs of a flea infestation. You want to be able to head off any potential problem as early as possible.

How Can an Indoor Cat Get Fleas?

You may think and indoor cat cannot get fleas, but that is not true. Fleas love animals and there are ways that your beloved indoor fur baby can come down with these awful pests. Here are 5 ways your indoor pet can get fleas.

From another pet – If you have other pets that go outside, they can bring these beasts inside and they can transfer to your indoor pet. Any pet your cat comes in contact with that has been outside or in contact with another outdoor pet, can be carrying fleas.

From another person – If a person has been in an environment where there are fleas or ticks, the person can be a carrier for fleas that can transfer to your pet.

Rodents can bring parasites indoors – Fleas like fur and anything that has fur can carry fleas. If by chance, you have rodents living anywhere in your home, your cat has the potential to get fleas from them.

A visit to the vet or a boarding facility – Anytime your cat comes in contact with another pet and you don’t know about the other pet’s environment, there is a chance your pet can pick up these pests.

You move into a new home – even if you do not see fleas in the new home, it does not mean there are not dormant fleas living there. It is a good idea to treat the home before you move in. If there are fleas in it, you will be glad you did (1).

9 Signs Your Cat Could Have Fleas

It should not be hard to tell if your cat has fleas. There are several signs that will tell you that your cat is being annoyed by these pesky parasites. Here are several signs that your cat needs to be treated for fleas.

Excessive Scratching and Biting – One of the first signs your cat may have that indicates fleas is scratching or biting of their skin and fur. Flea bites cause itching and this is your cat’s reaction to a body that itches.

Excessive Grooming and Hair Loss – The itching is so bothersome to your cat that they lick constantly to try to relieve it and that can cause bald spots. The base of the tail and the back of the legs are the hot spots.

Avoiding Areas of Your Home – If your cat starts to avoid certain areas in your home, they may be avoiding the fleas. Carpet and furniture are the environments that fleas like the most.

Red Skin Lesions or Scab-Like Bumps – Cats can have a reaction to flea saliva resulting in lesions that are red and inflamed. This can lead to a condition called flea allergy dermatitis. Your cat can end up with oozing sores and become fatally anemic if the condition is severe.

Agitation, Edginess and Restlessness – Being bitten by fleas and itching all the time can cause a change in behavior. Think about how a person would feel if they were being bitten continuously. The fleas drive your pet crazy and they may shake their head, rub their body on the floor or run around erratically.

Red Spots in Your Cat’s Bedding Fabric – This is evidence of flea dirt that has fallen off your cat. The moisture from the cat’s body causes the spots to turn and look like dried blood spots.

Muscle Loss, Pale Gums and Lethargy – These symptoms can result from anemia. Flea anemia can be fatal and is caused by an excessive amount of fleas biting your cat deeply leading to excessive bleeding.

Tiny Pepper-Like Specs on Your Cat’s Fur – These specs are flea dirt and composed of dried blood. They are often found on their neck and back.

Pinhead-Sized Specs Crawling on Your Cat’s Fur – Sometimes these critters will jump off your cat. They are easiest to spot on your cats next. If you part the fur, you should be able to see them crawling on your cat’s body (2).

Types of Flea Treatments for Your Cat

Flea treatments for cats come in several forms. As a cat parent, I look at safety, ease of dosing and effectiveness with safety being at the top of the list. Ease of usage is also very important.

If my cat is majorly stressed or I get torn to shreds during the application, I may opt for something that may be a little less effective but a little more user-friendly. Here are several types of flea medications that are available to assist in ridding your cats of fleas.


Collars used to be the way to go and they are still a great solution for killing your cat’s pests. Flea collars for cats are advertised as being effective for 6+ months for most brands. There are two types of collars.

Repellant collars emit a gas that deters fleas and ticks from biting. Treatment collars contain medication that is absorbed into the sebaceous glands and spread using the natural oils in a cat or dog’s skin.

If you are using a collar that repels, a parasite must bite your pet for the pesticide to kill it. Treatment collars release ingredients that kill fleas and ticks on contact before they bite.


Flea shampoos are another option for your cat or dog. Cat flea control shampoos get good reviews for effectiveness. Flea and tick shampoos primarily kill fleas and ticks that are already on a pet, through contact.

They would not be nearly as easy as applying a topical medication. It is cost-effective, especially if you have several pets that need flea relief. A shampoo treatment can usually be used once a week. The manufacturer’s instructions are your best guide.


Pills are very fast-acting. Fleas start dying within 30 minutes and 90% can be dead within 6 hours on a cat. There is no mess and there is no potential for hair loss as with some of the topicals. If you can get your cat to take a pill, an oral flea treatment for cats can be an option for you.

Powders and Sprays

Powders and sprays are applied directly to your cat and massaged into their skin. Some powders and sprays can be used in your home. They are a good option for kittens and senior cats. Here is a flea and tick powder for cats.

Food Additives

This is a powder that is taken orally. It can be sprinkled over your cat’s food. It is designed to create an odor that humans cannot smell, but it repels fleas and ticks, mosquitoes, and black flies. Your cat will no longer be appealing to these pests. Check out flea and tick internal powder for cats.

Topical Drops

Topical flea treatment is a flea medication that is applied to your cat’s skin. It is usually put on the back of your cat’s neck in a line. Topical flea treatment for cats had become popular due to its effectiveness and ease of application. It works quickly (in 30 minutes) and is only needed once a month (3).

How to Apply Topical Flea Treatments

Topical flea drops are an easy way to give your cat a flea treatment each month to ensure he remains happy and flea-free. Here are some simple to-follow instructions for applying topical flea medication.

How to Treat Your Home for Fleas

Getting rid of fleas is a 2 part process. You have to eliminate these pests on your pet and in your home as well. If your pet has an outdoor bed, you may want to treat it as well in an attempt to keep your cat more comfortable. Here are some steps you can take to eliminate fleas in your home.


Vacuum once a day. Sweep furniture, crevices, cracks and other areas where eggs can rest. Sweeping with also suck up live fleas. Make sure to dispose of the sweeper bag or clean the canister well to get rid of the fleas that were swept up once and for all. Your vacuum can be your best friend during this time.

Wash Clothing

Wash bedding, furniture covers and other fabric that your pet came in contact with once a week. Use hot water to kill the fleas. Be sure to do this with clothing as well.

Treat all Areas

Bombs, powder and sprays can help you get a fresh start. You and your pets will have to leave while this treatment is in process. You may have to repeat the treatment 3 – 4 weeks later to completely break the cycle of flea development. Be sure and follow the manufacturers’ instructions for use. 

Treat Your Cat

It is important that your pet and your home get treated at the same time so that both can be pest free.

Work with an Expert

Vets and exterminators can help you beat this problem. If you need help, be sure to get it for the health and comfort of you and your cat.

Final Thoughts

Flea treatments for your cat is necessary, but knowing which one to use isn’t always a simple decision. Your cat’s safety and comfort should come first.

Knowing your pet, you may realize that your cat may tolerate some types of flea treatments better than others. Some cats will not take pills. Others may be sensitive to chemicals.

Make sure you understand how your flea treatment of choice will work on your cat. Pay close attention to your cat for the first hour or two after administering a treatment so you can react to any adverse reaction he may experience. The best way to keep a cat flea-free is through a monthly maintenance treatment.
